OUTPUT SPECIFICATIONS
DESCRIPTION
The WRB-YES-1W&WRB-YES-2W series
are specially designed for applications where a
group of polar power supplies are isolated from
the input power supply in a distributed power
supply system on a circuit board.
These products apply to:
1) where the voltage of the input power supply is
wide range (voltage range ≤2:1);
2) where isolation is necessary between input
and output (isolation voltage ≤1500VDC);
3) where the regulation of the output voltage and
the output ripple noise are demanded.

No parallel connection or plug and play.
Note:
1. The load shouldn't be less than 10%, otherwise ripple will increase dramatically.
2. Operation under 10% load will not damage the converter; However, they may not meet all specification listed.
3. All specifications measured at Ta=25℃, humidity<75%, nominal input voltage and rated output load unless otherwise specified.
4. In this data sheet, all the test methods of indications are based on corporate standards.
5.Only typical models listed, other models may be different, please contact our technical person for more details.
